Environmental protection agency to continuously kill bacteria that pose a threat to human health.
No other touch surface material has this kind of registration.
The pure copper sheets were rolled with a small strain in one pass at cryogenic and room temperature respectively.
Five different processes plus variations within those five processes are used to form copper.
The copper forming process.
The microstructural evolution and mechanical properties of cu sheets were investigated by metallographic characterizations tensile tests and fracture analysis.

Hot rolling is carried out at temperatures above the recrystallization temperature of the metal.
The concept is similar to the rolling of dough rolling is classified according to the temperature of the metal rolled.
Additional information on physical properties and cold rolled tempers is available in data sheets from material suppliers asm metals handbook volume 2.
The recrystallization temperature is that temperature at which the crystal lattice structure of the metal.
This booklet will serve to answer immediate questions about using copper and copper alloys in familiar ways and in.
If the temperature of the metal is above its recrystallization temperature then the process is.
In metalworking rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform.
Hot rolling is carried out at temperatures above the recrystallization temperature of the metal.
